African fat-tailed gecko · UVB and shade
African fat-tailed gecko care should include the measured low-output UVB gradient below. Preserve complete shade and switch every light off at night.
The amount reaching the gecko changes with its distance from the lamp and anything positioned between them.

The short answer
African fat-tailed gecko care should include the measured low-output UVB gradient below. Preserve complete shade and switch every light off at night.
The honest fit
For an African fat-tailed gecko, use gentle product-specific linear UVB over part of the warm side with complete shade and secure dark retreats. Group the brighter zone with daytime warmth while preserving dark retreats and foliage or hide cover nearby.
A lamp percentage cannot predict the dose on its own. Follow the fixture maker's distance chart, account for mesh, and measure at the highest place the gecko can actually reach when possible.
Run the daytime lighting on a timer for roughly 12 hours, then make the enclosure dark overnight. Replace the lamp on schedule or verify output with an appropriate meter.
Secure or guard fixtures so the gecko cannot contact hot glass or a breakable lamp. After rearranging climbing routes or hides, re-check distance and shade instead of assuming the old setup still applies.
UVB, heat, calcium, and the rest of the diet work as one husbandry system. More supplement is not a safe substitute for unmeasured lighting, and more UVB is not automatically better.
Discuss supplement choice with a reptile veterinarian, especially for a red-eyed or unusually light-sensitive morph, a growing juvenile, an egg-producing female, or a gecko showing weakness or skeletal change.
